RELATED APPLICATIONS

This application claims priority to U.S. Patent Application Ser. No. 60/940,599, entitled “QUERY GENERATION SYSTEM FOR AN INFORMATION RETRIEVAL SYSTEM,” which was filed on May 29, 2007.

TECHNICAL FIELD OF THE DISCLOSURE

This disclosure generally relates to computing systems, and more particularly, to an query generation system for an information retrieval system and method of use.

BACKGROUND OF THE DISCLOSURE

Information retrieval systems are provided to assist in the retrieval of information from various types of computing systems. The Internet generally includes a network of computing systems providing readily available information that may be relatively diverse in content. Information retrieval systems that provide search capabilities of information contained on the Internet are commonly referred to as search engines.

SUMMARY OF THE DISCLOSURE

According to one embodiment of the disclosure, a query generation system generally includes an element rank and inference engine in communication with a computing system and a user interface. The element rank and inference engine is operable to receive a user supplied element from the user interface, the user supplied element being associated with a first filter criterion. The element rank and inference engine is also operable to create, using the first filter criterion, at least one second element and rank according to their relative importance, the at least one first element and the at least one second element according to their associated first filter criterion and second filter criterion. Next, the element rank and inference engine may output the at least one first filter element and the second filter element to the computing system.

Some embodiments of the invention provide numerous technical advantages. Some embodiments may benefit from some, none, or all of these advantages. For example, according to one embodiment, the query generation system may simplify the automatic visual generation of a modifiable data object that may be derived from user supplied elements. This automatic visual generation may include modification of various visual aspects of elements displayed upon a display. For example, the filter criteria of each element of the data object may modified by manipulating the spatial order, the color, the size, the shape, the order, the relative proximity, the boldness, and/or texture of one element relative to another. By manipulation of the various visual aspects of elements, the user may be able to easily tailor filter criteria of each element to enhance the filtering capability of the information retrieval system.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Information retrieval systems, such as search engines, have provided one approach for finding desired information from the vast information available on various distributed computing systems, such as the Internet or corporate networks referred to generally as intranets. The typical search engine usually functions by retrieving information based upon one or more text elements commonly referred to as keywords. Due to the relatively diverse nature of information provided by the Internet, however, results provided by known search engine implementations may include information that is beyond the scope desired by the user. That is, filtering of the relatively broad array of information available from the Internet using only keyword filtering may yield inadequate results in some cases.

FIG. 1 shows one embodiment of an query generation system 10 that may provide enhanced search capabilities than those provided by known information retrieval systems. Query generation system 10 generally includes an element rank and inference server 12 and an element rank and inference engine 14 that are in communication with a user interface 16, a search engine 18, and a database 20. As will be described in detail below, the query generation system 10 is operable to enhance filtering of information provided by search engine 18 to user interface 16 by inferring additional elements, creating super elements, and/or ranking elements according to their relative importance. In this manner, results provided by search engine 18 may yield results that are relatively more pertinent to the type of information desired.

Element rank and inference engine 14 may be any suitable algorithm that may infer additional elements, create super elements, and/or rank these elements according to those provided by a user through the user interface 16. In one embodiment, element rank and inference engine 14 incorporates a latent semantic analysis algorithm. The latent semantic analysis algorithm uses vectoral analyses to conceptualize terms and their relationship to one another among a number of documents or records in a computing system. For a computing system such as the Internet, the element rank and inference engine 14 may be operable to filter available information in an enhanced manner.

Element rank and inference server 12 is operable to receive requests in the form of user supplied elements from the user interface 16, interact with element rank and inference engine 14 to derive other elements, such as inferred elements and/or super elements, and issue these elements to search engine 14 as a request for filtered information. In one embodiment, element rank and inference engine 14 and element rank and inference server 12 may be implemented with a processor executing computer instructions stored in a memory.

The one or more elements including user supplied elements, inferred elements, and/or super elements may be referred to as a data object. A data object may be any type of object that can be stored or processed within a computer. That is, each element may be a portion of a data object that can be stored or processed within a computing system. For example, each element may include a keyword, phrase, paragraph, or an entire document. The element may also include a photograph, an icon or other visual object having filterable characteristics. For example, a photograph or icon may include metadata having filterable characteristics useful for the element rank and inference engine 14. Further, each element may have user selectable filter criteria that may enable the user to tailor the rank or other characteristics of the elements. These filter criteria may include, for example, a spatial order, a color, size, a shape, an order, a relative proximity, a relative boldness, a relative texture of each of the elements relative to other elements.

User interface 16 generally includes an interactive element display portion 22 and a result display portion 24 that may be executable on a computing system, such as a desktop computer, laptop computer, personal digital assistant (PDA), or other similar device. The interactive element display portion 22 and a result display portion 24 may be in communication with element rank and inference server 14 using any suitable approach. In one embodiment, interactive element display portion 22 and a result display portion 24 may be in communication with element rank and inference server 12 using a communication link, such as, for example, an Ethernet link. In another embodiment, interactive element display portion 22 and a result display portion 24 may be executable on the same computing system as element rank and inference server 12 such that communication may be provided by internal system calls. In one embodiment, database 20 may be included for storage of data objects for use at a later time.

When a data object including a number of user supplied elements are inputted by the user, the element rank and inference engine 14 may create inferred elements, super elements, or rank any of these elements according to their relative importance. The user supplied elements along with the inferred elements and super elements are displayed upon the user interface 16. In this manner, the user may modify various visual aspects of each of the displayed elements. For example, a change in the size of a particular element may represents a change in importance, such that increasing the size of the element increases the Element rank and decreasing the element size decreases the rank of the element.

The changing of other attributes could have other meanings and purposes. Another example could be that within the Query Cloud representation the user is able to mark particular elements as required by attaching a specific symbol to the respective visual object; this would result in the particular element being required in each query results. Other symbols would have other meanings and purposes. The user may also able to add and remove elements to the data object.

In one embodiment, the user interface 16 may be able to suggest additional inferred elements or super elements, as well as keep track of removed elements for re-inclusion, into the data object at a later time. Another example contemplates arrangement the proximity of one element to another so that the elements must occur within the represented proximity within each given query result. At any point the user can submit the data object to the search engine 18, at which time the data object converted into a query that the search engine 18 understands. The results provided by the search engine 18 may be displayed on the result display portion 24 of the user interface 16. In one embodiment, the data object may be saved and loaded for later use.

Search engine 18 may operate in conjunction with any suitable computing system for retrieval of information. In one embodiment, search engine 18 is operable to retrieve information from a distributed computing system, such as the Internet or an intranet that may be implemented in a corporate network.

FIG. 2 is a flowchart showing one embodiment of a series of actions that may be performed by the query generation system 10 to provide enhanced search results of information available from a computing system. In act 100, the process is initiated. In act 102, the user may enter one or more elements into the user interface 16. Once entered, the one or more elements are then received by element rank and inference server 12.

In act 104, element rank and inference engine 14 interacts with element rank and inference server 12 by ranking the one or more elements according to their relative importance. In act 106, element rank and inference engine 14 may extract one or more super elements from two or more elements of the data object. A super element is generally referred to as a particular element that is combined from two or more elements such that the super element has a new or enhanced meaning. For example, the element rank and inference engine 14 may be operable to derive patterns, phrases, colloquialisms, or other language aspects of multiple elements in order to form a super element that may enhance the filtering capability of the query generation system 10. In act 108, element rank and inference engine 14 may create one or more inferred elements from the one or more elements. An inferred element generally refers to elements that are not in the one or more user supplied elements, but are determined to be related by the element rank and inference engine 14.

In act 110, element rank and inference engine 14 may output the data object including the user supplied elements, any super elements and/or inferred elements created by the element rank and inference engine 14 to the user interface 16. In act 112, the user may optionally modify elements in the data object by submitting additional user supplied elements or manually modifying existing elements in the data object.

The data object including user supplied elements, super elements, and/or inferred elements may be modified to enhance various filter criteria of the element. In one embodiment, each element of the data object may be modified by manipulating a particular visual aspect of the element on the user interface 16. For example, the user may include a “*” character next to a particular element to indicate that the particular term is a required field. As another example, the font of an element may be enlarged or reduced to modify its relative importance relative to other elements in the data object. In one embodiment, elements may be removed from the data object by the user. In another embodiment, these removed elements may be stored for inclusion back into the data object at a later time.

If the user desires no further modifications to the elements in the data object, processing continues at act 114 where a query is generated based upon the elements and transmitted to a search engine 18. The results returned by the search engine 18 may be displayed on the result display portion 24. Given these results, further filtering of the data object may be obtained by repeating actions 102 through 112 as needed or desired. At act 116 the process may be halted by interrupting element rank and inference engine 14 and element rank and inference server 12 and/or by removing power from the computing system.

FIG. 3A through 3D are screenshots showing several example of a user interface 16 for displaying elements and providing interaction with the query generation system 10 of the present disclosure. Search engine 18 may be any suitable system for receiving requests including filter criteria and serving filtered information in response to those requests.
